摘要：
During tyre building, a crown structure is built through the actions of: forming at least one belt layer on an auxiliary drum for manufacturing a belt structure at least partly; turning up axially opposite side flaps of said at least one belt layer formed on the auxiliary drum; transferring the belt structure from the auxiliary drum to at least one service drum; and forming a tread band by winding of at least one continuous elongated element of elastomeric material into coils disposed mutually adjacent around the belt structure carried by the service drum.
